It’s 9:00, the police archives are opening their doors. Valentin, trainee for the production company «Boom of knowledge», is waiting outside the entrance. He’s a little stressed out because he has only one day to discover and understand who Ravachol was. He must gather all the documents that will allow to realize the story book of a documentary on the life of this man who gave trouble to the Prefecture of Police! We can say that the validation of Valentin’s internship depends on this day... Come help Valentin and dive into the history of anarchism in Paris through the sources of the Archives of the Prefecture of Police!
